tjh 555 Posted October 7, 2007 Share Posted October 7, 2007 I have bought a 200tdi engine and box to fit into my series three 109". The box is the 'short stick' out of the discovery though which puts the gear lever too far back. Is there an easy way to convert it? Can i just use the linkage off a defender or do i need to 'fabricate' something? Cheers, Tim. Quote Link to comment Share on other sites More sharing options...
GBMUD Posted October 8, 2007 Share Posted October 8, 2007 IIRC you need the top housing from the Defender as it is different. What do you propose to do about your front axle? Chris Quote Link to comment Share on other sites More sharing options...

FridgeFreezer Posted October 8, 2007 Share Posted October 8, 2007 You need to pull the whole back of the box off and change the tail casting, shift linkage, and the shifter link on top, you can't just swap the top piece - ask me how I know...

sean f Posted October 8, 2007 Share Posted October 8, 2007 Just to back up what has already been said. To convert the gearbox you will need to pull it apart (special puller required) and rebuild it with bits from a defender box. Friend did this for me a few years ago but it was only worth it because my defender box was knackered and he had a disco box sat there. You are probable better of getting a second hand defender box or seeing if a reconditioning place will take yours as an exchange unit, depends on your budget. The tranfer box is the same though except the disco will have a 1.222 ratio box and the defender should be 1.410, again you are probable better of with the defender transfer box especially if you are running big (more than 205) tyres as other wise the gearing is a bit tall.

FridgeFreezer Posted October 8, 2007 Share Posted October 8, 2007 What do you propose to do about your front axle? IIRC some on here are running LT230's and series front axles without problems. Then again, the 2WD conversion is easy. Quote Link to comment Share on other sites More sharing options...
GBMUD Posted October 8, 2007 Share Posted October 8, 2007 Stage 1 front axle is OK. On a series you are starting with 4.7 diffs so a 1.2 transfer box should be fine. Chris Quote Link to comment Share on other sites More sharing options...

Chris if anything, with a 1.2 t/box you will be undergeared, i run one and have rebuilt axles to 4.1 diffs Quote Link to comment Share on other sites More sharing options...
sean f Posted October 9, 2007 Share Posted October 9, 2007 GBMUD and Tonk are correct about the gear ratios, I forgot it was going into a series so would have 4.7 diffs not 3.54 as standard. Quote Link to comment Share on other sites More sharing options...
